Lake Minnetonka's Zebra Mussel Habitat Suitability Study
In 2010 the MCWD conducted a study of how well Lake Minnetonka's habitat is suited for zebra mussels. The water conditions in 22 out of 26 Lake Minnetonka bays that were assessed in this study have conditions that can support moderate to optimal zebra mussel growth based on high calcium concentrations (used for shell growth) and moderate chlorophyll concentrations, which provide a suitable food source from algae. The lake bottom conditions (substrate) are dominated by sand out to the mudline, where sediments then transition to muck. This is not optimal for zebra mussels but will support moderate growth.
